FIELD OF THE INVENTION

The present application relates to compounded compositions, methods of making compounded compositions, and methods of using compounded compositions to treat or prevent an infection. More specifically, the present application relates compounded topical nail compositions, methods of making compounded topical nail compositions, and methods of using compounded topical nail compositions to treat nail infections.

BACKGROUND

The body normally serves as host for a variety of bacteria and fungi. Most of the time, the balance between the body as host and the microorganisms is maintained. However, there are times when the physiological, biochemical, and/or environmental conditions permit the microorganisms to tip that balance, thereby causing an infection.

Nails and surrounding tissues are susceptible to many types of microbial infection. For example, bacterial nail infections include paronychia, which may also be related to viral infections. Certain fungal infections known as tinea infections are caused by mold-like fungi that thrive in warm, moist areas, thriving on the dead tissues of hair, nails, and outer skin layers. Tinea infections include tinea unguum, onychomycosis, affects the fingernails or toenails. Tinea infections are contagious and can be passed through direct contact or by contact with clothing, from shower and pool surfaces, and even from pets. Reoccurrences of nail infections are often frequent. For some subjects, such as those also diagnosed with diabetes or circulatory problems, or obese subjects, tinea infections and their treatment can be quite serious. In general, there are at least 3 different types of nail infections caused by fungi. The most common infection is frequently caused by Trichophyton rubrum and affects the nail bed and the area beneath the nail. Another type of infection affects only the nail surface and creates white or light colored patches. This second type of fungal infection is unusual and represents only about 10% of the reported cases. A third type of fungal infection affects the nail root and usually afflicts persons with impaired immune defense. A fourth (and unusual) type is caused by an infection of yeast fungi. Infections by yeast most often only affect nails that already are infected or damaged in some way.

The fungi are invasive to the keratin nail tissue. Apart from becoming discolored and brittle, the nail may often separate from the nail bed. In addition, pain and difficulty in wearing foot apparel is often experienced. Initially, the disease affects only one nail, typically one nail of the foot, and is thereafter spread to more nails. The palms of the hands and the soles of the feet may frequently be affected as well. When the skin is affected, red spots frequently occur and the skin may peel off. Nail fungal infections are one of the hardest forms of external infection to treat, of which infections of toe nails are the most difficult to treat.

Methods of Treating A Bacterial or Fungal Nail Infection

A method of treating a bacterial or fungal nail infection may include topically applying any topical nail composition disclosed herein. For example a topical nail composition may be directly applied to an affected nail surface. In some embodiments, topical administration to the affected nail surface may include layering or coating the nail surface with the topical nail composition. The topical nail composition may be applied directly to the nail surface via a brush, sponge, dropper, syringe, or other applicator. In one example, the topical nail composition may be painted onto the nail surface. The topical nail composition may be administered 1 to 4 times daily or as otherwise directed to treat the nail infection.

According to one embodiment, a method of pretreating a bacterial or fungal nail infection may include applying a solution containing a NSAID and DMSO to a nail before applying the topical nail composition to the nail. The solution containing the NSAID and DMSO may be as described herein. For example, the solution may include one or more NSAIDS selected from oxicams, such as meloxicam and piroxicam; salicylic acid derivatives, such as aspirin, diflunisal, salsalate, and trilisate; propionic acids, such as flurbiprofen, ibuprofen, ketoprofen, naproxen, or oxaprozin; acetic acids, such as diclofenac, etodolac, indomethacin, ketorolac, nabumetone, sulindac, and tolmetin; fenamates, such as meclofenamate; and/or COX-2 inhibitors, such as celecoxib, rofecoxib, and valdecoxib. In one embodiment, the NSAID includes diclofenac. Diclofenac may be present in an amount between approximately 0.05% and approximately 5% such as between approximately 1% and approximately 3%, between approximately 1% and approximately 2%, or approximately 1.5%. DMSO may be present in an amount between approximately 10% and approximately 50%, such as between approximately 15% and approximately 50%, between approximately 20% and approximately 50%, between approximately 25% and approximately 50%, between approximately 30% and approximately 50%, between approximately 35% and approximately 50%, between approximately 40% and approximately 50%, or between approximately 20% and approximately 40%.

This specification has been written with reference to various non-limiting and non-exhaustive embodiments. However, it will be recognized by persons having ordinary skill in the art that various substitutions, modifications, or combinations of any of the disclosed embodiments (or portions thereof) may be made within the scope of this specification. Thus, it is contemplated and understood that this specification supports additional embodiments not expressly set forth in this specification. Such embodiments may be obtained, for example, by combining, modifying, or reorganizing any of the disclosed steps, components, elements, features, aspects, characteristics, limitations, and the like, of the various non-limiting and non-exhaustive embodiments described in this specification.

The grammatical articles “one”, “a”, “an”, and “the”, as used in this specification, are intended to include “at least one” or “one or more”, unless otherwise indicated. Thus, the articles are used in this specification to refer to one or more than one (i.e., to “at least one”) of the grammatical objects of the article. By way of example, “a component” means one or more components, and thus, possibly, more than one component is contemplated and may be employed or used in an application of the described embodiments. Further, the use of a singular noun includes the plural, and the use of a plural noun includes the singular, unless the context of the usage requires otherwise. Additionally, the grammatical conjunctions “and” and “or” are used herein according to accepted usage. By way of example, “x and y” refers to “x” and “y”. On the other hand, “x or y” refers to “x”, “y”, or both “x” and “y”, whereas “either x or y” refers to exclusivity.

Any numerical range recited herein includes all values and ranges from the lower value to the upper value. For example, if a concentration range is stated as 1% to 50%, it is intended that values such as 2% to 40%, 10% to 30%, 1% to 3%, or 2%, 25%, 39% and the like, are expressly enumerated in this specification. These are only examples of what is specifically intended, and all possible combinations of numerical values and ranges between and including the lowest value and the highest value enumerated are to be considered to be expressly stated in this application. Numbers modified by the term “approximately” are intended to include +/−10% of the number modified.

The present disclosure may be embodied in other forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be had to the following claims rather than the foregoing specification as indicating the scope of the invention. Further, the illustrations of arrangements described herein are intended to provide a general understanding of the various embodiments, and they are not intended to serve as a complete description. Many other arrangements will be apparent to those of skill in the art upon reviewing the above description. Other arrangements may be utilized and derived therefrom, such that logical substitutions and changes may be made without departing from the scope of this disclosure.
